Abstract

Secure localization in wireless sensor networks (WSNs) has received a great deal of attention with the increasing applications of wireless sensors. Security issues of localization in WSNs need to take into account attacks from both external and internal nodes. In this paper, we propose a secure localization scheme based on trust evaluation called trust based secure localization (TBSL) to evaluate the trust of beacon nodes through detecting the identity and the behavior of such node and using the credible position information for localization in WSNs. Simulation results show that our proposed scheme can improve the accuracy of localization in a hostile environment.
